Claims.

An object of this inventionis to disclose an adjustable support which issimple, inexpensive and suitable for a wide variety of situations. Ithas been used in connection with lamp housings for ceiling illuminationand is therefore illustrated and described in that connection.

Further and other objects and advantages will be apparent from thespecification and claims, and from the accompanying drawing whichillustrates what is now considered the preferred embodiment of theinvention.

Figure 1 is a sectional view of a lamp housing set in a ceiling openingand supported in accordance with my invention; and

Fig. 2 is a View on line 2-2 of Fig. 1.

In the drawing, I0 is a ceiling having upper and lower surfaces I2 andI4, respectively, and provided with an opening framed by angle irons I6,I8, in which is supported a housing containing a lamp 20.

The housing has walls 22, a top 24, and a bottom in the form of a plate26 overlapping the lower surface I4 of the ceiling. Plate 26 has anopening 28--28 and may support a glass sheet 30 simply overlappingopening 28 on all sides thereof as shown, or the glass may be hinged inposition. The color and other characteristics of the glass are, ofcourse, suitable for the intended purpose. A reflector 32 directs thelight from lamp downwardly through glass 30 and opening 28.

The housing is supported by a suitable number of levers 34 passingthrough openings 3B in walls 22. The outer ends of arms 34 rest on angleiron I6 and the inner ends are adjustably carried by the heads 38 ofscrews 40 which pass through clearance holes 42 in levers 34 and arethreaded into the upper arm of angle brackets 44, the vertical arms ofwhich are fast to wall 22 and rest on levers 34.

To adjust the position of the housing it is only necessary to move glassaside in order to reach and turn screws with a screw driver and therebyadjust the housing to its desired position, after which the glass isrestored to its position and the installation is ready for service.

In operative position of the housing the ceiling opening is closed byplate 26 and no screws or adjusting devices are visible, but theconcealed adjusting screws may be instantly reached when desired, asabove described.

Levers 34 draw plate 26 tightly against surface I4 and the xture istherefore firmly clamped in its operative position.

It is to be understood that the invention is not limited to the speciiicembodiment herein illustrated and described, but may be used in otherways without departure from its spirit as defined by the followingclaims.

I claim:

l. A lamp housing, in combination with means for supporting said housingin an opening in a ceiling, said means comprising levers extendingthrough the walls of said housing and resting on said ceiling, each ofsaid levers being a bar used to exert a force at one point of itslength, by application of a force at a second, and turning at a thirdpoint which is its fulcrum, and means securing said levers to saidhousing after the latter has been completely mounted in the ceiling.

2. A lamp housing, in combination with means for supporting said housingin an opening in a ceiling, said means comprising levers extendingthrough the walls of said housing and resting on said ceiling, saidlevers being adjustable at their ends within said housing, each of saidlevers being a bar used to exert a force at one point of its length, byapplication of a force at a second, and turning at a third point whichis its fulcrum, and means securing said levers to said housing after thelatter has been completely mounted in the ceiling.

3. A lamp housing, means for supporting said housing in an opening in aceiling, in combination with means comprising levers extending throughthe walls of said housing and resting on said ceiling, each of saidlevers being a bar used to exert a force at one point of its length, byapplication of a force at a second, and turning at a third point whichis its fulcrum and each of said levers being adjustable by a screw en-`gaging its inner end and threaded into a support xed in said housing.

4. A lamp housing having an outwardly extending bottom plate, incombination with means for supporting said housing in an opening in aceiling, said supporting means comprising levers operative above saidceiling for clamping said bottom plate rmly against the lower surface ofsaid ceiling, each of said levers being a bar used to exert a force atone point of its length, by application of a, force at a second, andturning at a third point which is its fulcrum, and means securing saidlevers to said housing after the latter has been completely mounted inthe ceiling.

5. A lamp housing, means for supporting said housing in an opening in a,ceiling, in combination with means comprising levers extending throughthe walls of said housing and resting on said ceiling, each of saidlevers being adjustable by a screw engaging its inner end and threadedinto an angle bracket Xed to an inner wall of said housing, the lowerend of said bracket being adjacent the wall opening provided for saidlever, whereby the lower end of said bracket may serve as a pivot aboutwhich said lever is adjustable by said adjusting means.
